Launching Fragments With Fragmentscenario

Category: Advertising  ·  Sub-category: ads-misc  ·  Last updated:
Use this skill to test a `Fragment` in isolation using `FragmentScenario`, `launchFragmentInContainer<F>()`, and `launchFragment<F>()`. Covers the `androidx.fragment:fragment-testing` + `androidx.fragment:fragment-testing-manifest` artifact split, the `EmptyFragmentActivity` host (`android:Theme.WithActionBar` parent — not AppCompat), the `themeResId` override, the `FragmentFactory` survival across `recreate()` via the ViewModelStore-backed holder, the `containerViewId = android.R.id.content` vs `0` distinction (in-container vs headless), and the `findNavController()` limitation. Use when the user reports `You need to use a Theme.AppCompat theme (or descendant)`, `Fragment ... does not have a NavController set`, `Cannot set initial Lifecycle state to DESTROYED for FragmentScenario`, or asks "how do I test a fragment in isolation" / "headless fragment test".

From the source SKILL.md

FragmentScenario hosts a single fragment inside an internal EmptyFragmentActivity so the fragment's onCreate / onViewCreated / lifecycle can be exercised without a real screen. Two entry points exist: launchFragmentInContainer<F>() adds the fragment to android.R.id.content (full lifecycle including view), and launchFragment<F>() attaches it with no container (headless). The default theme extends android:Theme.WithActionBar, NOT AppCompat — overriding via themeResId is required for any AppCompat widget. This skill encodes the two artifacts, the theme trap, and the navigation limitation.
